Chipmaker announces $3 billion investment as demand for high-bandwidth memory continues to accelerate
Micron Technology (MU) shares climbed more than 4% on Thursday as investor enthusiasm around artificial intelligence infrastructure continued to fuel gains across the semiconductor sector.
The rally extended beyond Micron, with other AI and memory-related companies including Sandisk, Western Digital, Marvell Technology, Broadcom, Intel, and AMD also moving higher. The gains reflect growing confidence that demand for advanced chips and memory solutions will remain strong as AI adoption expands globally.
A major factor behind the latest move was renewed optimism around the AI memory market following reports that South Korea’s SK Hynix received strong institutional demand for its U.S. IPO. The interest signaled that major investors remain bullish on companies supporting the rapid growth of artificial intelligence computing.
Micron added to the momentum by announcing plans to invest up to $3 billion to strengthen the U.S. semiconductor supply chain. Part of the investment will support GlobalWafers’ silicon wafer manufacturing operations in Texas, expanding domestic production capabilities.
As part of the partnership, Micron and GlobalWafers are expected to enter a 10-year supply agreement, providing Micron with reliable long-term access to critical silicon wafer capacity used in semiconductor manufacturing.
The AI boom has become one of the biggest drivers of growth for chip companies this year. Demand from AI data centers has created a shortage of high-bandwidth memory (HBM), a specialized type of memory essential for powering advanced AI systems.
Companies such as Micron, Samsung Electronics, and SK Hynix have benefited significantly from this supply-demand imbalance, with investors expecting limited HBM availability to continue through 2027.
While semiconductor stocks have already delivered strong gains, Wall Street remains focused on whether AI infrastructure spending can continue supporting long-term growth across the industry.
